Abstract

PURPOSE: To provide a treatment method for org. waste which decomposes the org. waste by microorganisms while protecting the org. waste against a high-moisture state. CONSTITUTION: The treatment of the org. waste is executed by decomposing the org. waste 3, such as a garbage added with microorganisms, to water and carbon dioxide in a main body 2 while agitating the org. waste 3 within the main body 2. At this time, the air in the main body 2 is circulated and is heat exchanged with an evaporator 12, by which the moisture in the air is condensed and is discharged to the main body 2. The dried air from which the moisture is removed from the evaporator 12 is partly discharged outside the main body 2 via a deodorizer 22. The air corresponding to the discharged air is taken into the main body 2 from outside the main body 2.

[0009]

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes an organic waste treatment device for decomposing organic waste such as raw garbage (remaining rice, noodles, fish, vegetable scraps, meat, fruits, eggshells, fish bones) into, for example, water and carbon dioxide.

Reference numeral 2 is a main body, and the main body 2 stores an organic waste 3 such as raw garbage and has an air intake port (not shown).

The main body 2 is provided with an input port 2a for inputting organic waste 3 such as raw garbage, an input door 2b for opening and closing the input port 2a, and a discharge door 2c for discharging the solid matter remaining after processing to the outside of the main body 2. Have In addition, depending on the case, in the main body 2 and the insertion port 2a
A crusher (not shown) is provided at a position facing the crusher, and the organic waste 3 with large lumps of meat, bones, etc., introduced by the crusher 3
May be crushed. The crushed organic waste 3 is the main body 2
The organic waste 3 therein is decomposed and dropped into a chamber to be treated.

A rotary shaft 5 is provided slightly above the center of the main body 2, and the rotary shaft 5 rotates via a motor 6 with a reduction gear, a sprocket 7, and a chain 8.
The rotating shaft 5 is provided with a plurality of stirring means (for example, paddles 9) for stirring the organic waste 3.

The main body 2 is provided with temperature adjusting means for adjusting the temperature inside the main body 2 to a constant value (for example, 40 ° C. to 60 ° C. at which the activity of microorganisms becomes active). This temperature adjusting means is performed, for example, by turning the heater 10 on and off by a heater 10 and a thermostat (not shown) that detects a set value.

A circulation passage 11 for circulating the air in the main body 2 is provided above the main body 2, and openings at both ends of the circulation passage 11 face the inside of the main body 2. In the circulation passage 11, a moisture removing means for removing moisture in the air in the circulation passage 11 (for example, an evaporator 12 which is a component of the refrigeration cycle), and air for which the moisture has been removed by the moisture removing means are heated. Air heating means (eg, condenser 13, or
Heaters (not shown) are sequentially provided along the air flow in the circulation passage 11.

A drain pan 14 for receiving condensed drain water is provided below the evaporator 12, and the drain water flowing into the drain pan 14 is discharged to the outside of the main body 2 through a drain passage 15. Reference numeral 16 is a compressor that compresses the refrigerant flowing in the evaporator 12 and the condenser 13.

A fan 17 is provided in the circulation passage 11 to suck the air in the main body 2 into the circulation passage 11 and discharge the air to the outside of the circulation passage 11.

The circulation passage 11 is branched from the middle, and the circulation passage 11
There is provided an exhaust passage 20 for removing the water in the air inside by the water removing means and then guiding a part of the air heated by the air heating means to the outside of the main body 2. An exhaust fan 21 and a deodorizer 22 are arranged in the middle of the exhaust passage 20.

Although the inside of the deodorizer 22 is not shown,
For example, divalent iron or activated carbon is formed into a granular shape, and the granular shapes are laminated. When a fluid passes through the gap, the odor contained in the fluid is decomposed or absorbed.

When the fluid is moist, moisture adheres to the surface of the ferric iron or granular activated carbon formed in a granular form,
Although the deodorizing function is reduced, in this embodiment, the deodorizer is used.
Since the air passing through 22 is dried by removing the moisture by the evaporator 12, it is possible to prevent the deodorizing function from being deteriorated and obtain a deodorizing effect with certainty.

Further, the main body 2 is provided with humidity adjusting means for adjusting the humidity inside the main body 2 to a constant value. The humidity adjusting means is performed, for example, by turning on and off the compressor 16 using an evaporator 12 and a humidity sensor (not shown) that detects a set value.

Therefore, the organic waste 3 such as raw garbage is put in the inlet.
It is introduced into the main body 2 via 2a, and the introduced organic waste 3 contains microorganisms (for example, a group of microorganisms mainly composed of aerobic bacteria, product name AO.
Add a microbial activator (trade name AK-2) that activates the functions of bacteria and microorganisms.

Then, when the motor 6 with a reduction gear is operated, the rotary shaft 5 is rotated and the organic waste 3 is stirred by the stirring means (for example, the paddle 9).

When the organic waste 3 is stirred, the decomposition of the organic waste 3 is promoted and the decomposition is made uniform, and the organic waste 3 is decomposed into water, carbon dioxide gas, and a small amount of solid content.

Incidentally, as the organic waste 3 is decomposed, the main body 2
Although the inside becomes hot and humid as it is, in this embodiment, the air inside the main body 2 can be maintained at an appropriate humidity by operating the fan 17 provided in the circulation passage 11.

That is, the air sucked into the circulation passage 11 by the fan 17 exchanges heat with the evaporator 12 to condense the moisture in the air into drain water, and the drain water is drain pan 14,
It is discharged to the outside of the main body 2 through the drain passage 15. As a result, water (steam) generated by the decomposition of the organic waste 3
Will be discharged to the outside of the main body 2 as drain water.

Then, the moisture-free air from which moisture in the air is removed is heated by an air heating means (for example, the condenser 13 or a heater (not shown)) and supplied into the main body 2. That is, the water (or steam) generated by the decomposition of the organic waste 3 is removed by the evaporator 12,
It is recirculated into the body 2 as dry air.

The carbon dioxide gas generated by the decomposition of the organic waste 3 is exhausted from the middle of the circulation passage 11.
The air will be discharged from the outside of the main body 2 from 20.

Since a relatively small amount of air is discharged from the exhaust passage 20 to the outside of the main body 2, the odor is relatively small, and fresh air corresponding to the discharged air is taken from the outside of the main body 2 through the air intake port. It is introduced into the main body 2 via (not shown) to promote decomposition by microorganisms.

When the air is discharged, the air discharged from the deodorizer 22 has a certain deodorizing effect because the moisture is removed by the evaporator 12 and the air is dried. Prevents the discharge of offensive odors.

Further, since the main body 2 is provided with a temperature adjusting means and a humidity adjusting means capable of adjusting the temperature to be constant, the temperature adjusting means and the humidity adjusting means are provided. By adjusting, the decomposition state of the organic waste 3 can be observed. Then, based on the observation result, the type of organic waste 3, the optimum humidity and the optimum temperature according to the type of microorganisms can be determined, and after the determination, the humidity and temperature in the main body 2 are maintained at the determined values. If so controlled, the generation of odor can be suppressed as much as possible.
